The top rule for using any rat trap is to use plenty of traps.You may need more traps than you think is warranted when trapping rats. Usually, the population is larger than expected.
Make sure that you are trapping rats and not mice. A typical mouse trap is not big enough to trap rats.
Place rat traps in high-activity areas of the rat colony. These areas may include darkened corners, along walls, behind appliances and objects, and all areas where droppings are evident. Since rats need to touch surfaces as they move, place them accordingly.
Place rat traps spaced from 15-20 feet apart. Remember to place them touching a wall, since rats like to run along walls in order to avoid detection.
Since rats prefer enclosed, safe locations, use Protecta Bait Stations with the T Rex Snap traps. This will shelter the rat; encouraging it to enter and protect non targeted animals and children from harm of the snap trap. The Victor Snap Traps are fine traps, but its height will not fit into bait stations. If this is the case, you can get a cardboard box, cut holes in it and place it over the Victor Snap Trap. This method is not tamper resistant, however.
Position rat traps to maximize the chances of rats to cross over the traps during their natural travels along their runways. Set snap traps extended at a right angle from a wall with the trigger end almost touching the wall. If rat traps are set parallel to the wall, set them in pairs with triggers situated to intercept the rats from either direction.
To trap Roof Rats, set traps on tree limbs, under vegetation on a backyard fence or trellis, or on other aboveground locations roof rats are known to frequent. Traps can be fastened with wire to overhead pipes, rafters and beams.
Rats are often shy of new objects and the placement of unset traps in a new location for a week or two will increase the opportunities of catching.
Set out unset rat traps can be buried in grain, sawdust, or similar materials within a empty cardboard box or pie pan. Place the rat bait in small pieces near it and above it with the hidden trap below. Once the rats start taking the bait, set the traps.
This will acclimate the rats to the traps, once acclimated, set enough traps to kill the a large percentage of the population before the rodents become "trap shy" . This is called mass trapping, trapping them at a higher rate than they can repopulate and become shy of the trap.
There may be a need to have as many as 2-3 dozen rat traps set in
place in a commercial establishment, in an infested trash room, for
By having these rat traps baited with Provoke Rat Attractant or
peanut butter unset, a large population would be use to feeding on
around the traps. When the rat traps are then simultaneously set after
a while of this "feeding", a large kill can be obtained.
